Application file(l November 24, 1883. (Model.)

[O view of 'uhe hanger; Fig. 3, an enlarged view of the wheels and oonneooing-bar; Fig. 4, an enlarged view of the'outer doorplate; Fig. 5, another form of inner plate.

My invention relates to that dass of (100r- I hangers by whioh a door is susp'ended upon a wheeled oarriage trzweling upon an overhead trackway parallel with the floor or ceiling,the door being suspended by devices adjustably attaohed to its top cenbrally between its edges als 01 near each end of the top, so that the door hangs perpenclieularly ancl does not tonch the floor.

I consists of the several deviees and comloinations of cleviees hereinafter speeifically lt; is eonstructed as follows: A is a double praekway extending aoross and above the (100rway,0f any orclinary construetion,withasuffioient spaee between the rails to readily reoeive 0 the top of the door 0r that pa1b of the hanger by whiol1 it 1's suspencled, ancl permib II; to travel freely between the1n. B is the door. O C are tl1e carriage-wheels, usuolly construeted with a flange, and moun ted with the 3 5 flanges on oho inside, so (hat they pass along D is the suspenthe inner side of each mil. sion=frame, of about oho outline shown in the drawings, having one leg, a, pivotally comneoted or hingecl 150 the inner door-plate, b, in

or beoween the ears c, ancl having the other leg, d, oonnected 130 he plate e by bhe adjustq- Ing rocl or holt h,which screws upwarcl through the leg, as shown. 'Ihe door-plate b is simply a fiat piece of metal with the upright lugs 01 ears c upon its upper sicle upon 01 adjacent fits loosely betiveen (or in) the ears, ancl he pivotal holt asses throngh it and the ears,

w, upon its outer end. This head is coneaved in the end, und. a hole of oblong forn1 is made through the Shell of the head somewhat larger both ways than the bocly of the holt h, so that this holt fits loosely in this hole and is permitted to play therein,the hole not being large enough o0 pass the head of the holt through it. lhe upper end of this holt sorews into a hole in the leg d. The body of this plate is convex upon its outer faee, so that when the screwholes are bored through it ab right angles 130 the faoe the screws, when inserted, will enter the top of the (loor more or less obliquely,and not perpendicularly, and thus salze a stronger hold upon the wood, and. their supportingpower will be greatly increased. These legs a d a1e construoted of Ehe general form shown in the clmwings, und are usually integral wit-h the body m of tl1e frame D. In this body a groove is cut perpendieularly of sufeient depth and widoh to freely receive the counect-ingloar or reaeh o. Through this body, ab the proper point, I make a hole, r, through Whioh Ehe axle s of the bar 0 passes. This hole is also consicleraloly larger ohan the axle s, so that the axle can play therein, es hereinafter clesoribed. 'lhe axle s fits tightlyin the bar o. This bar 0 is construot-ecl of a fiel; pieee of metal of geneml oval form, or with its edges rouncling ouoward more or less, an(l has the bearings x upon it, one upon eaeh end, in which bearings the wheels G are journalecl in eny ordinary manner, the wheels standiug in planes respeotively parallel With IOO the door, thereby raising the door to the distance above the fioor desired. The position of the head. 0f the holt in the concavity 0f the head i enables me 110 adjust the height 0f the (1001 above the floor by simply passing a sorew-driver upwaid through ehe door-s1ot in the casing in which the top of the (1001 lies.- Then as the whee1s travel on the tracks they readily pass over any unevenness of surface, adjustsing themselves thereto by the consequent rocking of ohe bar 0 in the body m upon the ax1e s,which ax1e plays around in the hole 1 as the bar rocks. The bar 0 rocks whenever either of the whee1s connected so it is raised 01 depressed from any cause. 'Ihe resulb of this rocking movement is thab the door is earried along smoothly and in a perpendicular osition without swinging laberally, and 110 side gu'ide-rollers are necessary. 'lhe hingeconnection of the leg a.to the p1ate b enables me to raise 01 10wer the leg d, and this, in connection with the rocking of the bar o, renders my whole device flexible and yielding.

What I elaim as my invention, and desire t0 Secure by Letters Patent, is

1. In a double-track door-hanger, the combination of a supporting-frarne centrally secured to the top edge of ehe door, a rocking carriage pivotally connected to said frame, and two track-wheels journaled in said carriageone in front and the oher in the rear frameone in fronn and the other in rear of the point of oscillabion-as shown and described.

3. In a doorhangerthe frame D, cons tructed wioh tw0 legs a d, in combination with an inner p1ate, b, 150 which one leg 0f 1;he frame is connected, the parts being constructed, subsbantially as shown and described,to engage by a hook-eonnecnion,wher'eby provision is made f0r attaehing the frame while the d0or is in positi0n, substantially as described.

In witness whereof I have hereunto sei; my band this 22d day 0f November, 1883.
